It's amazing there are already so many years available for download.
Especially the larger zips must have been somewhat time-consuming to
compile! It would be great if 2008 or pre-2006 packages become available in
the near future. It is a really interesting development to see
being interested in not only compiling large
current packaged databases of various wikis, but also more historic
content. In the past, the Internet Archive was the sole distributor of
older (also historic) wiki packages.
Eventually in the far future, there will have to be some sort of viable
mechanism for cloning all the images stored on wikimedia, though as for now
the Picture of the Year packages are very interesting for those more
interested in the pretty images of wikipedia. The POTY images also make
great wallpaper packs!
